this question has answer here: what nullreferenceexception, , how fix it? 33 answers public class blah { public bool whatever { get; set; } public string whatyoujustsaid { get; set; } } public interface iblah { blah blahvalues { get; set; } } class class1:iblah { public blah blahvalues { get; set; } } and example: class1 c1 = new class1(); c1.blahvalues.whatyoujustsaid = "nothing"; c1.blahvalues.whatever = false; so how should change code blahvalues doesn't null? you have initialize blahvalues . using object initializer, can done below: class1 c1 = new class1() { blahvalues = new blah() }; as create c1 object, blahvalues it's default value, null . hence, when try assign value whatyoujustsaid , whatever null reference exception.

i have couple of files in repository change every other commit these changes literally don't change anything. let me explain. example, have file called ethereal following contents: foo bar kappa i make commit , mysterious entity changes file this: foo, bar, kappa these files exactly same project. the mysterious entity changes them no reason. here's thing: git doesn't know these files same. that's why every commit includes meaningless change of file ethereal . and no, adding .gitignore won't because ethereal has in project repository. the commit clutter becomes real problem. solution found typing git update-index --assume-unchanged ethereal before every commit. but read here not supposed often. imagine there 20 files that. there's gotta better way of dealing this. the mysterious entity changes them no reason. here's thing: git doesn't know these files same. git see content changed if single byte has been modi

i want filter wrong characters string (and replace them empty string later). tried making own regex expression have not succeeded make working. need javascript support. desired effect: com.12%example%.5a5pp => com.example.a5pp (regex matches: [1,2,%,%,5] ). you can find package name requirements here : a full java-language-style package name android application. name should unique. name may contain uppercase or lowercase letters ('a' through 'z'), numbers, , underscores ('_'). however, individual package name parts may start letters. i'm more familiar ruby myself, believe android apps written in java, , java can (?<) look-behinds. on assumptions, regex match incorrect character: /[^\w.]|(?<=^|\.)[^a-za-z]+/g you can plug 'replace' method replace match empty string. ( regex 101 place find meaning of each component of regex.) [update] javascript, doesn't support look-behinds, you'd have capture dot

in ios human interface guidelines under live photos section apple says this, "make sure users can distinguish live photo traditional still photo. it’s important users make distinction when can share photo. best way show users they’re viewing live photo display little movement gives hint of experience. in cases hint isn’t possible, can display system-provided badge on live photo. live photo never displays playback button looks video playback button." i kind of confused on how provide little hint of movement in live photo. how provide hint of movement? you don't need dissect live photo still frames , construct animated uiimage, or dig out live photo's movie file... it's simpler. display user's live photo content in phlivephotoview . call startplaybackwithstyle: , pass .hint playback style "hint" hig talking about. there's no step three.

what differences between following? type foo = { foo: string }; interface foo { foo: string; } interfaces can extended interface { x: number; } interface b extends { y: string; } and augmented interface c { m: boolean; } // ... later ... interface c { n: number; } type aliases, however, can represent things interfaces can't type numorstr = number | string; type neatandcool = neat & cool; type justsomeothername = sometype; so in general if have plain object type, shown in question, interface better approach. if find wanting write can't written interface, or want give different name, type alias better.

is there method query download item system downloadprovider,i that,but need permission:android.permission.access_all_downloads,and worstly,this permission in signature level,i can't permission,is there other solution this.and want develop app manager downloads of system.thanks lot! int columnid = c.getcolumnindex(downloadmanager.column_id); int columntitle = c.getcolumnindex(downloadmanager.column_title); log.d(tag, "query complete!-->" + c.getcount()); (int = 0; c.getcolumnname(i) != null; i++) log.d(tag, c.getcolumnname(i)); while (c.movetonext()) { int status = c.getint(c.getcolumnindex(downloadmanager.column_status)); long id = c.getlong(c.getcolumnindex(downloadmanager.column_id)); string title = c.getstring(c.getcolumnindex(downloadmanager.column_title)); switch (status) { case downloadmanager.status_paused:

i have set height on :root element, or else not viewport size want scrollbar. however, want set height: calc(100% - 130px); when viewport less 900px. how can since can not use @media query? tried no success: <template> <style include="iron-flex iron-flex-alignment"> :host[show] { background-color: var(--pink-color); width: 100%; overflow-x: hidden; overflow-y: auto; outline: none; display: flex; } :host[smallscreen] { height: calc(100% - 130px); } <div hidden$="{{!show}}"> <iron-media-query query="(max-width: 899px)" query-matches="{{smallscreen}}"></iron-media-query> ... <script> polymer({ is: 'video-selection', properties: { show: { type: boolean, value: true, reflecttoattribute: true }, smallscreen: { type: boolean,

how arrays.fill(char[] a,char val) implemented internally in java ? and complexity of it? if definition of fill(char[] a, char val) available in java.util.arrays class. it such this public static void fill(object[] a, object val) { (int = 0, len = a.length; < len; i++) //this loop continues length of a. a[i] = val; } so, complexity method o(n) . n length of object array object[] a passed parameter.

i new android. building first application. i have been trying make support multiple screens. have gone through developers section in android, but, not clear @ these things. what resolution, should use different drawable folders? (for example hdpi screen may have 500*600 screen or 1280*1920 screen.) i have been using layout folders mentioned in developers page, small, normal , rest, android keeps on selecting normal layouts screens nexus 6p(for guessing large appropriate). is there way make better?? have write layout once have define dimensions dimens.xml different different resolutions in app>res>values.
